Title: Apparatus for roughing surfaces of concrete casted blocks
Inventor: CICCARELLO CHARLES
IPC: B28D1/18
Filed: 2001-04-09
Abstract: An apparatus and method for roughing surfaces of concrete casted blocks are provided. A horizontally disposed surface roughing device, hawing impacting elements secured thereto, is driven to impact on blocks supported thereunder on a support table. The support table has a flat support upper surface. Block tilt support pins project from the upper surface at predetermined locations for supporting some of the blocks tilted at a predetermined angle. The block tilt support pins are displaceable from a retracted position below the upper surface to a projecting block tilting position above the upper surface. A displacement mechanism imparts translationary displacement between the impacting elements and the support table to abrade the blocks.

Abstract: A slip control article including a backing layer (21, 52) having a first surface (24) with an array of at least 15,5 upstanding stems (26, 56) per square centimeter and a second surface (25). At least a portion of the upstanding stems is an elastomeric material and the stems have an aspect ratio of at least 1.25. The first surface has a static coefficient of friction when dry of at least 0.6 and a static coefficient of friction when wet within 20 % of the static coefficient of friction when dry. The first surface has a peel strength and a tensile strength of substantially zero when engaged with another slip control article. The first surface has a relatively high shear strength when engaged with another slip control article. The high shear forces are due primarily to the frictional properties of the elastomeric materials, not a mechanical interlock of the stems, such as on a mechanical fastener.

Inventor: CHEN PHIL FU-WEI
IPC: H04W88/18
Filed: 2001-06-11
Abstract: Disclosed is a method for enhancing data wipeoff using predicted future navigation data and improved timing alignment. Proper time alignment of predicted future navigation data to the navigation data to be wipeoff enhances data wipeoff by reducing or eliminating the amount of incomplete wipeoff. In one embodiment, the future navigation data is predicted for a particular satellite and a first or starting bit in the predicted future navigation data is time aligned to a corresponding reference bit in the navigation data to be wiped off. Specifically, the transmission time at the satellite of the reference bit is determined and added to a propagation delay associated with the satellite to obtain an action time for applying the predicted navigation data at a GPS receiver or WAG client to GPS  signals transmitted by the satellite.

Title: Bus management method
Inventor: MATSUNO KATSUMI
IPC: G06F13/42
Filed: 1994-07-19
Abstract: One node is selected from a plurality of candidates for a bus management node. A bus management node 11 has a register for channels in use REG 1 and a bus capacity register REG2. Before starting the synchronous communication, each node 12 transmits a read-out command to the register for channels in use REG 1 and the register for channels in use REG1 in order to read out their contents for ascertaining the number of the un-used channel and the residual capacity. If there is any un-used channel and any residual bus capacity, the node 12 transmits write commands to these registers REG 1 and REG2 so that the number of the channel to be in use and the capacity of the bus to be in use will be stored in the register for channels in use REG 1 and the bus capacity register REG2. This enables bus management to be achieved easily in a system performing synchronous communication between plural nodes connected to the bus.

Abstract: In a WDM optical network, optical components of optical add/drop multiplexers (OADMs) at different nodes are made independent of the optical channel wavelengths to be dropped and added. Groups of optical channels each comprise a respective channel in each of a plurality of optical bands of channels having adjacent wavelengths, and the OADMs use tunable optical filters to drop and add channels in a selected group.      A remote source supplies unmodulated optical carriers at channel wavelengths via an optical carrier fiber to each node, and at least one, conveniently all, of the optical carriers in a respective optical band is/are modulated with a signal to be transmitted via the add filter.

Title: Freeform modeling method and system
Inventor: POLKE HANS
IPC: G06T19/20
Filed: 2001-10-01
Abstract: A method and system for use in freeform modeling of solids and surfaces in which multiple commands for modifying the geometry of an object can be designated to run concurrently, so as to greatly reduce the number of steps required of the user in the design process.   The method and system also allows commands to be designated as associative, so that the command is performed automatically whenever the geometry to which it is attached is modified. This leads to a further streamlining of the design process. The method and system also allows the user to store the interactive scene as it is at any given time, with the current selections and tool representations, so that the work can be resumed later without the user having to redo any interactions. With that, and in relation to parallel and associative commands, the system allows the user to capture all design constraints and dependencies throughout the whole lifetime of a design model.

Patent CA-2360924-A1 (CA)
Inventor: BARNES DAVID A
IPC: H01S3/038
Filed: 2000-01-20
Abstract: A method for forming an electrode seal between an excitation electrode and a laser block in a ring laser gyro having increased bond durability, strength, and greater resistance to solvents and reactive compounds. A thin ring of sealing material is positioned between an excitation electrode and a laser block of the ring laser gyro, and the sealing material is compressed. Chemical and physical bonds are formed between the excitation electrode and the sealing material and between the sealing material and the laser block. A pre-determined electrical potential is applied across the excitation electrode, the sealing material, and the laser block for a pre-determined period of time and at a pre-determined temperature. The electrical potential increases the number of chemical and physical bonds that are formed at the seal, thus increasing the bond durability and strength.
